What happened
Prior to departure, the aircraft was loaded with 140 gallons of Jet A fuel. During the initial climb phase following takeoff, both engines experienced a complete loss of power. Due to the low altitude of the aircraft at the time of the failure, the pilot was unable to perform a return to the departure airfield and instead performed an emergency landing in a nearby field. The impact caused significant damage to the left wing, which subsequently led to a post-crash fire.
Findings
Investigations revealed that the aircraft type's reciprocating engines had been improperly supplied with Jet A fuel instead of the required AVGAS. While the line service worker noted an absence of instructional decals at the fuel ports during the fueling process, investigators discovered an AVGAS specification decal on the right-wing port during the post-accident inspection. The condition of the left-wing fuel port could not be verified because the fire destroyed much of the left wing structure.
